Abstract
The invention relates to a first pushable transport cart which can be embodied as a shopping cart or baggage cart. The first pushable transport cart comprises contact elements. If the first pushable transport cart is pushed into a second corresponding pushable transport cart, the contact elements form an electric contact between the first and second pushable transport carts. Electric power can be supplied via this electric contact, whereby charging of a storage device of the first pushable transport cart from a storage device of the second pushable transport cart takes place using a charge flow management system.
Claims15
A pushable transport cart system comprising at least a first pushable transport cart and a second pushable transport cart, the first and second pushable transport carts comprising an electric storage device and an electric device and two contact elements, the two contact elements establishing an electric contact in a movement-controlled manner by an insertion movement of the first and second pushable transport carts into one another, wherein a connection is established between an electric connecting device of the first pushable transport cart and an electric connecting device of the second pushable transport cart and/or a stockage and/or charging station, wherein control logic is provided which provides a charge flow management in which a storage device of the first pushable transport cart is charged from a storage device of the second pushable transport cart.
